I looked everywhere , but could not find anything that would work. :'( How to install the mods (bikes, tracks, plugin, ...)?
I know you have to create a folder , but there is someone who tells me step by step. I have beta8.
Forgive me.
have a look here see if that helps.
(Installation from Mods, Tracks, Bikes etc only works with the full (bought) version)
